New Chiltern Railways Trains Set To Unlock 10,000 More Seats A Day
The title of this post is the same as that of this press release from Chiltern Railways.
This picture from Chiltern Railways shows the train at Marylebone.
These three paragraphs are from the press release and add more details.
Chiltern Railways today (Tuesday 14 October) showcased for the first time its newest (Mark 5A) trains, set to add 10,000 more seats for customers each weekday from December 2026.
The trains, to be introduced between London to West Midlands from early 2026, will enable Chiltern to deliver more capacity across each of its West Midlands, Aylesbury, and Oxford routes as part of the operator’s efforts to deliver better journeys for customers.
The newest fleet will consist of 13 modern trains set to transform customer journeys during 2026. The trains will replace Chiltern’s oldest carriages, which are nearly 50 years old, with state-of-the-art equivalents, and provide a significant improvement to the on-board experience.
Today, I also received an update from Modern Railways, which was entitled Chiltern Railways Mk 5As To Enter Traffic Early Next Year, and included this delivery schedule.
From December 2026 there will be ten Mk 5A sets in traffic each day, with one ‘hot spare’ and one undergoing maintenance. That leaves one extra set which, CR has suggested, could eventually be pressed into traffic.
I have a few thoughts.
How Do The Trains Compare Physically?
These are basic figures for the two different types of train sets.
- The current Mark 3 are five-car sets of 23 metres coaches, that weigh about 36 tonnes. The driving van trailer is 18.83 metres and 43.7 tonnes
- The future Mark 5A are four-car sets of 22.2 metres coaches, that weigh about 43 tonnes. The driving trailer is 22.37 metres and 43 tonnes.
Lengths and weights of various sets will be as follows.
- Mark 3 – five-car and driving van trailer – 133.83 metres and 223.7 tonnes.
- Mark 5A – four-car and driving trailer – 111.17 metres and 215 tonnes
- Mark 5A – five-car and driving trailer – 155.57 metres and 258 tonnes
Note.
- Chiltern Railways and TransPennine Express use the same Class 68 locomotives.
- The five-car Mark 3 and the four-car Mark 5A sets are quite similar in length and weight
- This could mean that both sets would perform similarly with the same locomotives on the same route.
- I wouldn’t be surprised that the new Platform 4 at Birmingham |Snow Hill station will be able to handle all configurations.
I almost feel that when CAF designed the Mark 5A sets for TransPennine Express, they also had Chiltern in mind as another possible sale.
How Many Trains Would Be Needed To Run Between London Marylebone And Birmingham?
Consider.
- Trains currently run half-hourly on the route between 06:00 to 23:30, which is up to 36 services per day.
- When Platform 4 is operational at Birmingham Snow Hill station, all services could probably stop at both Birmingham Moor Street and Birmingham Snow Hill stations.
- A round trip between London Marylebone and Birmingham Snow Hill stations currently takes about five hours.
I’m fairly certain that to run a half-hourly core service would need ten trains.
Could Chiltern Develop Another Network On The Other Side Of Birmingham?
Consider.
- Trains could run twice an hour from 06:00 to 23:30, which is up to 36 services per day.
- When Platform 4 is operational at Birmingham Snow Hill station, all services could probably stop at both Birmingham Moor Street and Birmingham Snow Hill stations.
- Chiltern Railways already run several services a day to Stourbridge Junction.
- Chiltern Railways have run services to Kidderminster station in the past.
- Wrexham & Shropshire used to run locomotive-hauled Mark 3 four-car sets with driving van trailers, as far as Wrexham via Shrewsbury.
It looks to me, that with the right rolling stock configurations, Chiltern’s network can be developed on the other side of Birmingham.
- Destinations could include Stourbridge Junction, Kidderminster, Shrewsbury, Wolverhampton, Chirk, Ruabon and Wrexham General.
- Some services would need longer trains.
Obviously services would only be run if they were viable.
Would It Help Growth In A Town Or Area, If It Had A Rail Connection To London And/Or The Nearest Major City?
I know Lincoln is on the other side of the country, but I asked Google AI if Lincoln’s rail link to London has brought growth to the city and received this answer.
Yes, Lincoln’s rail link to London has brought significant growth by improving tourism, business travel, and student mobility, and is expected to spur further economic benefits through faster journey times and increased services. The direct link has made Lincoln more accessible for visitors and is a key part of the city’s long-term strategy for economic growth and development.
That was fairly definite.
How would that apply to an extended Chiltern Main Line.
- Politicians are always saying growth is important.
- An extended Chiltern Main Line servicewould improve connections of a lot of places to London and Birmingham.
- Shrewsbury is the easiest connection for West Wales.
- Surely a rail connection to a major city, might tempt someone to open a branch or a new factory.
Would a rail service make people feel more included?
An Interesting Comment From Lord Peter Hendy
This article on Modern Railways is entitled Chiltern FINALLY Signs Mk 5 Deal.
This extract from the article describes the deal.
An agreement for Chiltern Railways to lease the Mk 5A coaches previously operated by TransPennine Express and owned by Beacon Rail Leasing has been signed – and the trains are due to replace the current Mk 3 stock in phases from 2026. A 10-year lease has been agreed for the vehicles.
Chiltern will take on all 13 five-car sets as well as the spare Driving Trailer and the dedicated pool of 14 Class 68 locomotives.
The article also, has this excellent quote from Lord Peter Hendy, who is the Rail Minister at the end.
This government is putting passengers back at the heart of the 21st century railway by investing to make journeys easier, greener, and more comfortable.
“We are continuing to support Chiltern as they develop a plan to introduce additional services into their timetable, giving people more opportunities to work, live, and socialise.
I agree with much of what Lord Peter Hendy says, but could we see some actions to back up the words.
I have a few thoughts.
Lumo To Glasgow
I wrote about this new service in Lumo Will Extend Its King’s Cross And Edinburgh Service To Glasgow.
Given the opposition of the Transport Minister to open access services, I didn’t think this innovative service would be approved.
- But it does add an affordable passenger-friendly service to London and Glasgow routes.
- It will certainly be an easier route to London for some in Scotland.
- It also adds some much-needed direct services between Newcastle and Glasgow.
Did Lord Peter Hendy have words to help Lumo get its approval?
As I wrote in Could London And Central Scotland Air Passengers Be Persuaded To Use The Trains?, I also believe that this new Lumo service could persuade more air passengers to take the train to Scotland.
Lumo To Stirling
I wrote about this service in ORR: Open Access Services Given Green Light Between London And Stirling.
- First Group has taken over Grand Union Trains and the service will now be run by Lumo, who will use diesel Class 222 trains.
- But Lumo will have the option of running their electric Class 803 trains on the route, as it is fully electrified, when their fleet receives more trains.
This was another service, that I didn’t think would be approved, as no other services on the West Coast Main Line were approved, as Network Rail objected.
But it certainly meets the words in Lord Peter Hendy’s statement.
Like Lumo’s service to Glasgow, when the Stirling service gets electric trains, it will surely cut carbon emissions of travellers to Central Scotland.
Chiltern’s Replacement Trains
Chiltern Railways are replacing this fleet of locomotive hauled trains.
- 8 Class 68 locomotives
- 25 Mark 3 coaches
- 6 Driving Van Trailers
As services between London Marylebone and Birmingham Moor Street stations consist of one locomotive, five coaches and one driving van trailer, that means there are two spare locomotives, one spare coach and one spare driving van trailer, if there are five rakes of coaches in service.
The new fleet will be.
- 14 Class 68 locomotives
- 52 Mark 5A coaches
- 14 Driving Van Trailers
If services between London Marylebone and Birmingham Moor Street stations consist of one locomotive, four coaches and one driving van trailer, that means there are one spare locomotive and one spare driving van trailer, which gives a possible thirteen rakes of coaches in service.
There are certainly enough to expand Chiltern’s services. The obvious destination would surely be Oxford. These pictures show the two North-pacing platforms at Oxford station.
The platforms would be shared with East-West Rail, but they are around 160 metres in length.
The Modern Railways article quote Arriva Group Managing Director UK Trains Amanda Furlong as saying this.
Upgrading our fleet is a vital next step in Chiltern’s modernisation plans and an important part of Arriva’s wider ambition to support the transition to more sustainable rail travel across the UK and Europe.
We are proud to support this important milestone for Chiltern Railways, which is a great example of what can be achieved through strong collaboration with Government to deliver practical improvements for passengers. We look forward to seeing these upgraded trains improve journeys and lower emissions across the network.
She certainly would agree on some issues with Lord Peter Hendy.
So will Chiltern Railways do something to reduce the carbon footprint of their fourteen Class 68 locomotives?
- The Class 68 locomotives don’t have too many miles on the clock.
- Chiltern have already run some their Class 68 locomotives on HVO, so this must be a possibility.
- In total there are thirty-four Class 68 locomotives in service all of which have Caterpillar engines, so a conversion to zero-carbon power could be worthwhile.
I asked Google for an AI Overview on How many diesel locomotives have caterpillar engines worldwide? I got this answer.
While a precise worldwide count of diesel locomotives powered by Caterpillar (CAT) engines is difficult to pinpoint, it’s estimated that hundreds, if not thousands, of locomotives are equipped with CAT engines. Caterpillar has a long history of supplying engines to the rail industry, with engines like the 3500 series powering both mainline and switcher locomotives. Additionally, CAT engines are also used in generator sets for Head End Power (HEP) in passenger locomotives.
Note.
- It appears that, Caterpillar might have given up making truck engines because of emission issues.
- London Marylebone and Oxford is 66.8 miles
- London Marylebone and Birmingham Snow Hill is 112.3 miles.
Perhaps one of the consultants like Ricardo could convert these locomotives to run on hydrogen.
TransPennine Express To Stop Using Loco-Hauled Push-Pull Trains In December
The title of this post, is the same as that of this article on Railway Gazette.
This is the sub-heading.
TransPennine Express has confirmed that it will cease using its push-pull sets of Class 68 locomotives and MkVa coaches, previously designated Nova 3 sets, from the December 2023 timetable change.
These are my thoughts.
The Nova 3 Trains
Currently, the Nova 3 trains are made up from the following.
- 14 – Class 68 locomotives
- 52 – Mark 5a coaches
- 14 – Driving Van Trailers
Note.
- There have been complaints about the noise of the Class 68 locomotives at Scarborough and also at Marylebone with Chiltern Railways.
- The Class 68 locomotives could be switched to freight duties.
- The coaches are capable of 125 mph.
- A maximum of thirteen sets can be created.
- I suspect CAF wouldn’t object to being asked to build some more Mark 5a coaches and driving van trailers.
- The current fleet has a spare locomotive and a spare driving van trailer to allow for servicing.
All locomotives and coaches are a maximum of seven years old, so will have plenty of life left.
The Class 93 Locomotive
Rail Operations Group have ordered ten Class 93 locomotives, with twenty options, which have an impressive specification.
- Built by Stadler in Valencia.
- Same family as a Class 68 and 88 locomotive.
- Electric, diesel and battery power
- 110 mph operating speed
- Ability to pull passenger and freight trains.
- Delivery scheduled for 2023.
I believe that if the Class 68 diesel locomotive of a Nova 3 train, were to be replaced with a Class 93 locomotive, a very useful train would be created.
- It would be ten mph faster, than a Nova 3 train.
- It could use the diesel engine and the batteries to bridge gaps in electrification.
- By adding extra carriages it could be tailored to the needs of a route.
- In Vegetable Oil Fuelling Chiltern Railways Trains In UK First, I discuss how it might be possible to run all these locomotives on HVO to cut emissions.
- It could be quieter.
Could it be a simple way to reduce carbon emissions on a route?
The Successor To The Class 93 Locomotive
Stadler keep innovating in their designs for locomotives and are already building hydrogen-powered multiple units.
I can see Stadler coming up with a hydrogen-powered locomotive, with the following specification.
- In the same family as Class 68, 88 and 93 locomotives.
- Ability to do everything that Class 68, 88 and 93 locomotives can do.
- Ability to use 25 KVAC overhead electrification, where it exists.
- Ability to be able to be fitted with third-rail equipment, so it can use 750 VDC third-rail electrification, where it exists.
- At least a 110 mph operating speed.
- Range of at least 200 miles on hydrogen.
Stadler would sell a lot of these locomotives to decarbonise railways all over the world.
Possible Routes
These are possible routes for a rake of Mark 5a coaches hauled by a Class 93 locomotive or its zero-carbon successor.
Hull Trains
Consider.
- Hull Trains is an open access operator.
- Hull Trains currently have a fleet of five Class 802 trains, each of which have five-cars.
- A Class 93 locomotive has a power of 900 kW on diesel, whereas the Class 802 train has 2100 kW.
- The Class 802 train has nearly ten percent more capacity.
- In Ten-Car Hull Trains, I saw two Class 802 trains working as a pair. Does this indicate they have a capacity problem?
- Between Hull and the East Coast Main Line is only 36.1 miles and isn’t very challenging and I suspect could probably be easily handled by a Class 93-hauled rake of Mark 5a coaches.
- Adding extra coaches would not be difficult and would probably be less costly than with the more complex Class 802 trains.
- Hull Trains need to have a plan to decarbonise.
- HVO could be used to cut down emissions.
A Class 93-hauled rake of Mark 5a coaches could be an intermediate step to full decarbonisation with a hydrogen locomotive.
Would other operators of Class 802 trains like to increase their fleets, by adding Hull Trains’s five Class 802 trains?
TransPennine Express
Consider.
- TransPennine Express currently have four different fleets of trains, so it must cause problems with the allocation of drivers.
- The Class 397 trains are confined to the West Coast Main Line.
- So that leaves the bi-mode Class 802 trains and the diesel Class 185 trains to work the TransPennine routes.
The Wikipedia entry for the Class 802 train, gives more details of the plans for the Class 802 trains.
During October 2021, it was announced that TransPennine Express, Hitachi, and Angel Trains had agreed to convert one of the former’s Nova 1 trainsets into a battery hybrid train on a trial basis with the aim of supporting the technology’s further development. If successful, Hitachi and Angel Trains have proposed the retrofitting of the entire fleet. In January 2022, reports emerged that the Nova 1 fleet was operating under diesel power even when operating on entirely electrified sections of the East Coast Main Line on account of the insufficient power supplies present along the line; national railway infrastructure owner Network Rail is reportedly set to complete upgrades to the power supplies within two years.
The fleet is also set to benefit from the rollout of electrification under the Transpennine route upgrade scheme. The company’s management has noted that, in the event of largescale electrification being funded and implemented, the Class 802s could have some of their engines removed to reduce roughly 15% of their weight and thus raise their efficiency. Furthermore, Leo Goodwin, TPE’s managing director, has observed that while the Class 802s have an initial maximum speed of 125 mph (201 km/h), they have the capability of being modified for operating at 140 mph (230 km/h) if infrastructure upgrades were to permit such speeds at a future date.
Could an augmented fleet of battery-electric Class 802 trains handle the bulk of the TransPennine routes, with the shorter and unelectrified ones still being handled by the Class 185 trains?
These shorter routes are.
- Leeds and Huddersfield
- Manchester Piccadilly and Huddersfield
- York and Scarborough
Plans only exist to electrify Leeds and Huddersfield.
I suspect a few more battery-electric Class 802 trains would be needed.
Great Western Railway
Could a Class 93-hauled rake of Mark 5a coaches be used as a replacement for the GWR Castles or short-formation InterCity125s?
- They both have four passenger coaches.
- They are both 125 mph trains.
- A Class 68 locomotive could be used on routes without electrification.
- HVO could be used to cut down emissions.
- The Mark 5a coaches would probably be quieter, as they only have one diesel engine.
A Class 93-hauled rake of Mark 5a coaches could be an intermediate step to full decarbonisation with a hydrogen locomotive.
Alternatively, five-car Class 802 trains could be used as replacements for GWR Castles.
Great Western Railway also have the problem of decarbonising services between Bristol/Gloucester and Weymouth/Southampton/Portsmouth.
Great Western Railway look like they’re needing some innovative thinking.
I also suspect a few more battery-electric Class 802 trains would be needed for other routes.
Transport For Wales Rail
Transport for Wales Rail run a Premier Service between Holyhead and Cardiff using Class 67 locomotives and Mark 4 coaches.
According to the Wikipedia entry for Transport for Wales Rail, they have seven sets of 4/5 coaches to run this service.
If Transport for Wales Rail wanted to decarbonise this route, they would need to replace the locomotives for a zero-carbon unit.
Perhaps, their best solution, would be to wait until a suitable hydrogen-powered locomotive is available and buy seven rakes of new coaches with driving van trailers.
Grand Union
Grand Union has a detailed Wikipedia entry, where this is the first paragraph.
Grand Union is a prospective open access operator who are proposing to operate train services in the United Kingdom from England to Wales and Scotland. Grand Union is headed by Ian Yeowart, who founded previous open access operators Alliance Rail Holdings and Grand Central before selling both to Arriva.
That seems a sound foundation.
- They have permission to run trains between Paddington and Carmarthen starting in December 2024.
- They have also applied to run trains between Euston and Stirling.
- They are now backed by Spanish companies; Serena Industrial Partners and Renfe.
- They are proposing to use nine Mark 4 coaches hauled by Class 93 locomotives.
Consider.
- CAF has a factory in Wales.
- CAF has sold trains to Transport for Wales.
- The Mark 5a coaches will definitely be available by December 2024.
- Mark 5a coaches could easily be arranged as a rake of eight coaches and a driving van trailer.
- Grand Union is backed by Spanish companies.
I wouldn’t be surprised if Grand Union were to use sets of CAF-built Mark 5a coaches for their Carmarthen service. And later for their Stirling service.
A Class 93-hauled rake of Mark 5a coaches could be an intermediate step to full decarbonisation with a hydrogen locomotive.
Grand Central
Consider.
- Grand Central is another open access operator.
- Grand Central has a mixed fleet of twelve five-car diesel trains.
- These trains run under electrification on the East Coast Main Line.
- According to the Wikipedia entry for Grand Central trains, they have plans for expansion across the North and to and from London.
- Grand Central need to have a plan to decarbonise.
- HVO could be used to cut down emissions.
A Class 93-hauled rake of Mark 5a coaches could be an intermediate step to full decarbonisation with a hydrogen locomotive.
South Western Railway
South Western Railway have an excellent fleet of new or nearly new trains, with the exception of the diesel Class 158 and Class 159 trains, that work services between Waterloo and Exeter trains via Basingstoke and Salisbury.
- Waterloo and Exeter is 172 miles.
- Only the 47.7 miles between Waterloo and Basingstoke is electrified with 750 VDC third-rail electrification.
- Train lengths vary between five and eight cars.
- The current trains date from around 1990 and must need replacing soon.
I wouldn’t be surprised that if after a rebranding with new trains, this could be a popular route.
A version of Hitachi’s ubiquitous bi-mode Class 802 could be used.
But.
- They would need to be ordered and built.
- The third-rail gear, would need to be developed and tested.
- Passengers would be travelling for over two and a half hours with underfloor diesel engines.
An alternative could be a Class 68-hauled rake of Mark 5a coaches.
- These trains would be available after release from TransPennine Express.
- They would run in TransPennine Express formation.
- Length could be adjusted by adding or removing coaches, if required.
- The noise is all in the locomotive, which is isolated from the passengers.
At some point in the future, the route could be decarbonised by swapping the locomotive for a hydrogen-electric locomotive with the ability to handle third-rail electrification.
ScotRail
ScotRail have a similar problem to Great Western Railway with their short-formation InterCity125s.
- They have 52 Class 43 locomotives and 120 Mark 3 coaches, which is probably enough for 24 trains.
- Scotland has substantial amounts of electrification.
- I feel that a Class 68-hauled rake of Mark 5a coaches would be a more than adequate replacement.
- Class 93 locomotives could be used where routes are partially electrified.
- Scotland is not going to be short of green hydrogen.
When a suitable hydrogen-electric locomotive is available, these trains can be decarbonised.
CrossCountry
CrossCountry have a fleet consisting of the following trains.
- 5 – 2+7 InterCity125 trains
- 7 – two-car Class 170 trains
- 22 – three-car Class 170 trains
- 34 – four-car Class 220 trains
- 4 – four-car Class 221 trains
- 20 – five-car Class 221 trains
Note.
- The fleet is all diesel.
- I’ll ignore the Class 170 trains in this analysis.
- The Class 220 and 221 trains often work in pairs to provide the required capacity.
So how could these trains be decarbonised?
- The InterCity125s and the Class 220 and 221 trains could be replaced by a locomotive-hauled rake of Mark 5a coaches of an appropriate length.
- Motive power could be provided by an appropriate Class 68 or 93 locomotive.
When a suitable hydrogen-electric locomotive is available, these trains can be fully decarbonised.
Decarbonisation Of UK Main Line Services
It is generally assumed that the railways of the UK will need to fully decarbonise if the UK and the constituent nations are going to meet their decarbonisation targets.
I believe that my analysis shows that decarbonisation of main line passenger services can be achieved by the purchase of two types of trains.
- Five-car bi-mode Class 802 trains or similar.
- Locomotive-hauled rakes of Mark 5a coaches of an appropriate length.
Note.
- The Class 802 trains would be mainly to augment existing Hitachi fleets.
- Some Class 802 trains would be fitted with batteries instead of diesel generators to handle gaps in the electrification.
- The rakes of coaches would be powered by an appropriate locomotive.
- The lengths of the rakes of coaches would be adjusted to meet the demand of each service.
Initially, the following locomotives would be used.
- Class 68 locomotives would be used on unelectrified lines.
- Class 93 locomotives would be used on full or partially electrified lines.
When the hydrogen-electric locomotives become available, these would take over the routes, which couldn’t be decarbonised by full electrification or by using a Class 93 locomotive.
DfT To Have Final Say On Huddersfield Rebuild Of Rail Station And Bridges
The title of this post, is the same as that of this article on Rail Technology Magazine.
This is the first paragraph.
As part of the £1.4bn Transpennine Route Upgrade. Transport Secretary Grant Shapps is to rule on planned changes to Huddersfield’s 19th century rail station and not the Kirklees council, in what is to be a huge revamp of the line between Manchester and York.
According to the article eight bridges are to be replaced or seriously modified.
As Huddersfield station (shown) is Grade I listed and three other Grade II listed buildings and structures are involved, I can see this project ending up with a substantial bill for lawyers.
But then, to have a world-class railway across the Pennines, a few eggs will need to be broken.
Electric Trains Across The Pennine
This page on the Network Rail web site describes the Huddersfield To Westtown (Dewsbury) Upgrade.
When the upgrade and the related York To Church Fenton Improvement Scheme is completed, the TransPennine route between Huddersfield and York will be fully-electrified.
As Manchester To Stalybridge will also have been electrified, this will mean that the only section without electrification will be the eighteen miles across the Pennines between Stalybridge and Huddersfield.
Will this final eighteen miles ne electrified?
Eighteen miles with electrification at both ends will be a short jump for a Hitachi Intercity Tri-Mode Battery Train, the specification of which is shown in this Hitachi infographic.
The Class 802 trains of TransPennine Express are able to be converted into these trains.
The trains could work these routes.
- Liverpool Lime Street and Scarborough
- Manchester Airport and Redcar
- Liverpool Lime Street and Edinburgh via Newcastle
- Manchester Airport and Newcastle
- Manchester Piccadilly and Hull
- Manchester Airport and Cleethorpes
Note.
- I suspect some more Class 802 trains with batteries will be needed.
- The trains would either use battery or diesel power to reach Hull, Redcar and Scarborough or there could be a few miles of electrification to stretch battery range.
- Will the Class 68 diesel locomotives be replaced with Class 93 tri-mode locomotives to haul the Mark 5A coaches to Scarborough.
- Manchester Airport and Cleethorpes could be a problem and will probably need some electrification around Sheffield and Grimsby.
This would just mean TransPennine’s two short routes to be decarbonised.
- Manchester Piccadilly and Huddersfield
- Huddersfield and Leeds
As except for the eighteen mile gap between Stalybridge and Huddersfield, these two routes are fully-electrified, I suspect that a battery-electric version of a 110 mph electric train like a Class 387 or Class 350 train could run these routes.
Conclusion
It looks like if these sections of the TransPennine Express network are upgraded and electrified.
- York and Church Fenton
- Huddersfield and Westtown
- Manchester and Staylebridge
Together with a few extra miles of electrification at strategic points, that TransPennine Express will be able to decarbonise.
My First Ride In A Nova 3 Train
Nova 3 is the name that TransPennine Express have given to their new fleet of Mark 5A coaches hauled by Class 68 locomotives.
The first few pictures were taken, when I saw a Nova 3 at Manchester Victoria station and the ither during and after a ride between Manchester Victoria and Leeds stations.
These are a few of my thoughts.
Comfort, Noise And Vibration
It was certainly good and up there with the best.
Tables For Four
There were quite a few tables, but not everyone got one.
Ride And Performance
There was nothing wrong with the ride, but we were only doing 75 mph across the Pennines.
Next time, I’m in the North, I’ll take one of these trains up the East Coast Main Line to Scarborough or Redcar to feel them at a faster speed.
Conclusion
I wouldn’t object to having these coaches with a Class 88 electric locomotive running between London and Nowich via Ipswich.
A Chaotic Morning Peak Across The Pennines
I had intended to ride in one of TransPennine Express’s new trains that are formed of a rake of Mark 5A coaches hauled by a Class 68 locomotive.
As they run between Liverpool Lime Street and Scarbough, I thought it best to buy a return ticket between Manchester Victoria and Leeds.
Problem Number 1 – Northern’s Ticket Machine
Northern’s new ticket machines are fine when they work, but for some reason they wouldn’t respond to my fingers.
I find this with some touch screens, which are mainly in Sweden or IKEA in the UK.
So I bought a ticket from the ticket office intending to catch the next Scarborough train.
This had also happened the day before at Leeds.
Problem Number 2 – The Scarborough Train Didn’t Arrive
As the Scarborough train didn’t arrive, I gave up and took the Newcastle train towards Leeds.
Problem Number 3 – Overcrowding At Huddersfield
I took this picture of the crowds at Huddersfield.
My phone was telling me that the Scarborough train was behind my Newcastle train, so I decided to change at Huddersfield.
But I made a mistake and got on a very crowded train, that was going to Hull via Leeds.
I had to stand to Leeds, but at least I got a roomy and safe standing space.
Problem Number 4 – Class 185 Trains
.The Class 185 trains are just three-cars and totally inadequate for the route.
The trains were ordered in 2003 and were delivered in 2006-2007.
If you read the section entitled Overcrowding And Passenger Feedback, in the Wikipedia entry for the trains., you’ll see from the early days, these trains did not have enough capacity for the route.
I blame the Treasury under Gordon Brown, who specified the trains and as with Class 700 trains, which were also specified by the Treasury, there are serious shortcomings.
Considering that among other routes at this time, the London and Norwich route was being run by eight car trains, what in heaven were they thinking about.
But it was only the North of England! And not London or Scotland!
Problem Number 5 – Crowded Leeds Station
Leeds station was crowded as ever, but it wasn’t helped by an escalator being broken down.
I had hoped, that I would have enough time to go to Harrogate, but I felt as it was all so slow, that it was best to go back to Manchester Victoria station, grab something to eat and then go on to Liverpool Lime Street station, which was my intended destination.
Problem Number 6 – Ticket Machine At Leeds Station
I needed a Single from Leeds to Liverpool Lime Street and try as I might, I couldn’t find it on the machine, so I resorted to the Ticket Office again.
Problem Number 7 – Train Failure At Manchester Victoria Station
The train from Leeds to Manchester Victoria was another Class 185 train and I did get a seat.
But where was the new five-car rake of Mark 5A coaches and a Class 68 locomotive?
I did successfully split my journey at Manchester Victoria station, but there seemed to be problems, so I thought I’d go on immediately to Liverpool and arrive in the city with an hour to spare for my meeting.
As if things could be so simple!
A Class 185 train had failed in the platform and it was nearly an hour, before I got away to Liverpool in a train, that arrived in the bay platform 2, which to get to the West, had to come out of the station and reverse. I suspect TransPennine Express were using a driver in both cabs or driving it from the Liverpool-facing cab at all time.
Problem Number 8 – Late Arrival Into Liverpool Lime Street
I arrived in Liverpool about fifteen minutes late for my meeting, with the rain chucking it down, after it being dry in Manchester.
The weather in itself must be unusual!
My Observations
I was having a text conversation with a friend in London and these were my observations to him, with a few other points added by hindsight.
1. Northern’s Ticket Machines
These need reeducation and the dry-finger problem that I suffer with the screens must be fixed.
2. Northern’s Ticket Offices
Northern needs to open more ticket office windows.
3. Where Is The London-Style Contactless Ticketing?
London has proven, that contactless ticketing based on bank cards increases passenger numbers and revenue and has a high level of passenger satisfaction.
\The area of the North between Liverpool and Blackpool in the West and Leeds and Sheffield in the East is in terms of passenger numbers smaller than London’s contactless ticketing area.
I think there are two reasons, why it doesn’t exist now or in the near future.
- The trains are not big enough to cope with the increased traffic.
- It will result in a reduction of ticket offices and their staff and those in charge are frightened of the RMT.
So visitors like me have to suffer an inadequate ticketing system because of timid management.
4. Buying Tickets In The North In The Future
In future, when I go to the North, I’ll plan my journey in detail and buy my tickets from the intelligent and extremely customer-friendly ticket machines in Dalston Junction station.
It’s strange that both Northern and the London Overground are run by Arriva. How can one get it so right and the other so wrong?
Perhaps it’s because the London Overground only deals with one organisation; Transport for London and Northern deals with a myriad rabble of councillors, MPs, pressure groups, all fighting their own corners.
5. All Trains Must Be At Least Six Cars
More capacity is needed and as there is a lack of train paths across the Pennines, because of lack of investment in the tracks for decades, starting with that enemy of the train; Harold Wilson.The simplest way to increase to increase capacity is to make all trains at least six cars.
But I would go father than that.
- Trains running across the Pennines should all be identical.
- Capable of at least 100 mph.
- Capable of 125 mph, when the route includes the West or East Coast Main Lines.
- Fast acceleration away from stops.
- Identical door configuration with wide double doors on all trains.
- Level access between train and platform.
- Short dwell times in stopping stations.
Identical trains improve timekeeping and give a better service to passengers.
If you look at the Paddington and Oxford service it is now run virtually exclusively using Class 800 or 802 trains. I feel as an occasional passenger that it has improved dramatically, in terms of capacity, comfort and reliability for passengers.
6. What Idiot Decided To Buy Three Different Fleets For TransPennine Express?
The sister company of TransPennine Express is Great Western Railway.
Great Western Railway’s main line services are run by two fleets of trains.
- Hitachi Class 800 and Class 802 trains for long distance services.
- Class 387 trains for electric commuter services.
As some of the Class 387 trains are being converted for Heathrow Express and Crossrail are taking over London and Reading services, I can see a time, when all fast services that go to and from Paddington through Reading will be run by the Hitachi trains.
Consider.
- West of Heathrow, the fast lines are reserved for the 125 mph Hitachi trains.
- The 110 mph Class 387 trains to and from Heathrow, don’t get in the way of the faster Hitachi trains.
- Applying digital signalling to increase paths on the fast lines is easier with identical trains.
- Driver training and rostering must be simpler.
It’s not perfect, but it’s an arrangement that can be made to work well.
If a unified fleet is so good, why did TransPennine Express buy three separate fleets?
Class 802 Trains
Nineteen Class 802 trains will be used for these services.
- Liverpool Lime Street to Edinburgh Waverley via Newcastle (from December 2019)
- Liverpool Lime Street to Newcastle (until December 2019)
- Manchester Airport to Newcastle
This seems to be a sensible and obvious choice.
- A five-car Class 802 train has eighty percent more seats than a three-car Class 185 train.
- A five-car Class 802 train is shorter than a pair of Class 185 trains.
- The trains are 125 mph trains, that can be upgraded to 140 mph with digital in-cab signalling.
- FirstGroup must have a large amount of experience of running Class 802 trains.
- Class 802 trains have an automatic split and join facility.
- East Coast Trains, Hull Trains and LNER will be running similar Hitachi trains on the East Coast Main Line.
In addition the fleet is future-proofed in two important ways.
- If the TransPennine route is ever electrified, their diesel engines can be removed.
- Extra cars can be added to Class 802 trains to increase capacity
Using Class 802 trains is an excellent choice.
Class 68 Locomotive And Mark 5A Coaches
Twelve rakes of four Mark 5A coaches between a Class 68 locomotive and a driving van trailer, will run these routes.
- Liverpool Lime Street to Scarborough via Manchester Victoria.
- Manchester Airport to Redcar Central (In 2019).
I wonder why these services aren’t going to be run by another twelve Class 802 trains.
Consider.
- Pollution would be reduced and the air improved in the electrified Liverpool Lime Street, Manchester Airport and Manchester Airport stations, if TransPennine used Class 802 trains on all services from the station.
- Drivers on the routes across the Pennines would more often be driving the same trains.
- The Class 802 trains are in service on the East Coast Main Line, which must make timekeeping better.
- The Class 802 trains can be upgraded to work at 140 mph on the East Coast Main Line.
It’s rather strange!
Class 397 Trains
Twelve Class 397 trains will be replacing ten Class 350 trains.
- The extra two trains are to provide a Liverpool and Glasgow service.
- The Class 397 trains have an extra car over the Class 350 trains.
- The seating capacity of both trains is 296.
- The Class 397 trains are 125 mph trains, which can mix it with Virgin’s Pendelinos.
- The Class 350 trains are only 110 mph trains, which must get in the way of the Pendelionos.
- I suspect that the Class 397 trains can be upgraded to 140 mph in the future.
The Class 350 trains needed to be increased and replaced with a 125 mph train.
But why aren’t they being replaced with more Class 802 trains?
- The Class 802 train is already in service.
- The Class 802 train has 326 seats as against the 296 of the Class 397 train.
- TransPennineExpress are already buying nineteen Class 802 trains.
- If required, an all-electric version could be ordered.
- West Coast Rail plan to run Hitachi trains on the West Coast Main Line.
It’s rather a puzzle, why TransPennine Express has ordered Class 397 trains, as everything suggests that Class 802 trains could run West Coast services.
All Three Fleets Use The Castlefield Corridor
Believe it or not, but TransPennine Express plan to run these services through the Castlefield Corridor.
- Manchester Airport and Glasgow/Edinburgh – Class 397 trains.
- Manchester Airport and Newcastle – Class 802 trains
- Manchester Airport to Redcar Central – Mark 5A coaches.
Three routes and three different trains!
Was this timetable chosen to confuse staff and passengers?
Possible Reasons For Three Fleets
The only valid reason is that the Hitachi trains can’t work in Scotland.
But it is more likely to do with production schedules at Hitachi or that the fleets were bought by accountants, with very little brain!
I did notice this statement in the Wikipedia entry for the Class 397 trains.
An option for up to 22 extra units was available to TransPennine Express, but it was not exercised.
As 22 trains is close to the nineteen Class 802 trains that were ordered, were TransPennine Express trying to buy a totally-CAF fleet?
7. Track Speed Should Be Improved
Track speeds are slow compared to say the the Great Eastern Main Line,
Improving the track to allow faster speeds may be one of the best decisions to take.
8. There Should Be Better Platform Access At Manchester Victoria And Leeds Stations
These two stations don’t have the best access to the platforms..
They should be improved with more escalators, so that passengers changing trains don’t miss their connections.
Conclusion
Money needs to be spent to remove some of the chaos and constipation in the North.
I
Puzzled By New Fleets For TransPennine Express
TransPennine Express (TPE) are replacing all their trains, but their choice of three different new fleets puzzles me.
The new fleets and their routes are as follows.
Nova1
This is a fleet of nineteen five-car bi-mode Class 802 trains.
According to Wikipedia, they will work the following routes, with probably a frequency of one tph
Liverpool Lime Street and Edinburgh via Newcastle, which I estimate will take 4:15 hours
Manchester Airport and Newcastle, which takes around 2:45 hours
These two services would probably need nine for the Edinburgh service and six for the Manchester Airport service.
This means that there are four extra trains.
If there is a spare or one in maintenance, that means that two trains are available to boost capacity on busy services if needed, by running a ten-car train.
I doubt that ten-car services to Manchester Airport could be run through the Castlefield Corridor due to the inadequate stations, but Liverpool and Edinburgh might be a route for longer trains.
I have some observations on Nova1.
- The trains are 125 mph trains, that can be upgraded to 140 mph with in-cab signalling.
- The trains will share the East Coast Main Line with LNER’s Azumas, which are other members of te same family of Hitachi trains.
The trains have been authorised to start running services.
Nova2
This is a fleet of twelve electric Class 397 trains.
According to Wikipedia, they will work the following routes,
- Manchester Airport and Glasgow Central, which takes around 3:30 hours.
- Manchester Airport and Edinburgh, which takes around 3:15 hours.
- New route – Liverpool Lime Street and Glasgow Central, which could take around 3:30 hours.
Currently, the two existing routes run at a frequency of one train per two hours, which would probably need at least seven trains.
This probably means that there will be four trains left for the service between Liverpool and Glasgow, if it assumed there is one train spare or in maintenance.
As a round trip between the two cities, would probably take eight hours, it looks like the frequency will be one train per two hours.
This would give the following services, all with a frequency of one train per two hours.
- Manchester Airport and Glasgow Central via Manchester Piccadilly
- Manchester Airport and Edinburgh via Manchester Piccadilly
- Liverpool Lime Street and Glasgow Central
Passengers wanting to go between Liverpool Lime Street and Edinburgh should keep reading.
I have some observations on Nova2.
- They are 125 mph trains that are replacing the 110 mph Class 350 trains.
- In the next few years, these 125 mph trains will be sharing the West Coast Main Line with faster trains like Class 390 trains and the trains of High Speed Two, both of which should be capable of 140 mph, when running using in-cab signalling.
- I would assume that the trains can be similarly upgraded, otherwise they will have to be replaced.
- There was an option for more trains, but I suspect the success of Class 802 trains on the Great Western Railway led to it not being taken up.,
The trains should come into service later this year.
Nova3
This is a fleet of five-car rakes of Mark 5A coaches, hauled by a Class 68 diesel locomotive.
There are fourteen locomotives and driving van trailers, with enough coaches for thirteen rakes.
I would suspect that TPE are aiming to have twelve trains available for service.
According to Wikipedia, they will work the following routes, which both have a frequency of one train per hour (tph)
- Liverpool Lime Street and Scarborough via Manchester Victoria, which takes around 2:45 hours.
- Manchester Airport and Middlesbrough, which takes around 2:45 hours.
So with turnround at both ends, I suspect that a six hour round trip is possible. So to provide the two hourly services across the Pennines, TPE will need six trains for each route.
This explains a fleet size of twelve operational trains.
I have two observations on Nova3.
- They are diesel-powered and will be running at times on electrified lines. But I suspect the diesel Class 68 locomotive could be replaced in the future with an electro-diesel Class 88 locomotive.
- Questions have been raised about the speed of exit and entry from the coaches through single end doors of the coaches.
- They have an operating speed of only 100 mph, but opportunities for higher speeds on the routes are limited to perhaps thirty to forty miles on the East Coast Main Line.
At least they should be in service within a couple of months.
Why Didn’t TPE Order A Unified Fleet?
To summarise TPE have ordered the following trains.
- Nova1 – Nineteen Class 802 trains
- Nova2 – Twelve Class 397 trains.
- Nova3 – Thirteen trains consisting of four coaches topped and tailed by a a Class 68 locomotive and driving van trailer.
All forty-four trains are five cars.
Surely, it would have been easier for TPE to have a fleet, where all the trains were the same.
I suspect that all routes can be run using Class 802 trains, so it as not as if there are any special requirements for the trains.
So why didn’t TPE order a fleet of Class 802 trains?
I can only think of these reasons.
- Hitachi couldn’t supply the required number of trains in the appropriate time-scale.
- ,CAF made an offer that TPE couldn’t refuse.
It should also be born in mind that Great Western Railway and Hull Trains, which like TPE are First Group companies, went down the Class 802 route.
The Future
There are various issues, that will arise in the future.
Nova2 And West Coast Main Line Operating Speed
The new Nova trains are running on TPE’s Northern and Scottish routes and as I indicated earlier, the Nova2 trains might not be fast enough in a few years time for the West Coast Main Line, which will have Class 390 trains running at 140 mph using in-cab signalling.
High Speed Two will surely make this incompatibility worse, unless CAF can upgrade the Nova2 trains for 140 mph running.
Replacing the Nova2 trains with Class 802 trains, which are being built for 140 mph running, would solve the problem.
Nova3 And Class 68 Locomotives
There are powerful reasons to replace diesel locomotives on the UK’s railways, with noise, pollution and carbon emissions at the top of the list.
As Northern Powerhouse Rail is created, there will be more electrification between Manchester and York, adding to the pressure to change the traction.
- There could be a change of locomotives to Class 88 or Class 93 locomotives, which would run using the overhead electrification, where it exists.
- The trains could be changed to Class 802 trains.
The Class 68 locomotive is increasingly looking like an interim solution. At least, it’s a less polluting locomotive, than the dreaded and ubiquitous Class 66 locomotive.
Class 185 Replacement
TPE will still have a fleet of diesel three-car Class 185 trains.
- They are running on routes between Manchester and Hull and Cleethorpes via Huddersfield, Leeds and Sheffield.
- These are best described as just-about-adequate trains and are one of The Treasury’s boob-buys.
- As Northern Powerhouse Rail is created, they will be increasingly running under wires.
- Could it be likely that more capacity will be needed on routes run by these trains?
- The capacity of a Class 185 train is 169 seats, as opposed to the 342 seats of a five-car Class 802 train.
I think it could be very likely that instead of running pairs of Class 185 trains, TPE will replace them with five-car Class 802 trains.
Conclusion
I very much feel, that over the next few years, TPE’s fleet will change further in the direction of a one-unified fleet!
Dwell Times And End Doors
Chris Stokes finishes his column in the January 2019 Edition of Modern Railways, with this paragraph.
Dwell times remain critical too. The new TransPennine units provide more seats, but have single end doors. For an operation with high numbers joining and alighting at many stops, dwell times are going to increase significantly at stations such as Manchester Victoria, Huddersfield, Leeds, Boltonand Preston, chewing up any savings in running times, and exacerbating the problems at platforms 13 and 14 at Manchester Piccadilly.
I haven’t seen a TransPennine Mark 5A coach in the flesh yet, but I’ve seen several pictures, which show each coach has single end doors.
This picture of the 100 mph Class 755 train shows the door layout is totally different.
It looks like it has a single double door on each coach.
It appears that the electric Class 745 trains have more doors.
If you look at a typical Bombardier Aventra or Electrostar, Stadler Flirt or Siemens Desiro City, there are generally no end doors.
Have CAF commited a design crime of the highest order?
Or is it TransPennine’s fault?
Stadler’s New Tri-Mode Class 93 Locomotive
In Thoughts On A Battery/Electric Replacement For A Class 66 Locomotive, I looked at an electro-diesel freight locomotive with batteries instead of a diesel engine, as a freight locomotive. It would have the size and weight of a Class 70 locomotive and perhaps use similar technology to Stadler’s Class 88 locomotive.
I concluded the article like this.
It would be a heavyweight locomotive with a performance to match.
I believe that such a locomotive would be a very useful addition to the UK’s fleet of freight locomotives.
Stadler have not produced a battery/electric replacement for a Class 66 locomotive, but they have added a diesel/electric/battery Class 93 locomotive with a heavyweight performance to their Class 68/88 or UKLIGHT family of locomotives built at Valencia in Spain.
Details of the locomotive are given in this article in Rail Magazine, which is entitled Rail Operations Fuels Its Ambitions With Tri-Mode Class 93s. There is also a longerand more detailed article in the print edition of the magazine, which I purchased today.
Reading both copies of the article, I can say the following.
A More Powerful Class 88 Locomotive
At a first glance, the Class 93 locomotive appears to be a more powerful version of the Class 88 locomotive.
- The power on electric mode is the same in both locomotives at four megawatt. It would probably use the same electrical systems.
- Some reports give the diesel power of the Class 93 locomotive as 1.34 MW as opposed to 0.7 MW of the Class 88 locomotive.
- The Class 93 locomotive has a top speed of 110 mph, as opposed to the 100 mph of the Class 88 locomotive.
- The article says, “It’s an ’88’ design with the biggest engine we could fit.”
It would also appear that much of the design of the two locomotives is identical, which must make design, building and certification easier.
The Class 93 Locomotive Is Described As A Hybrid Locomotive
Much of the article is an interview with Karl Watts, who is Chief Executive Officer of Rail Operations (UK) Ltd, who have ordered ten Class 93 locomotives. He says this.
However, the Swiss manufacturer offered a solution involving involving an uprated diesel alternator set plus Lithium Titanate Oxide (LTO) batteries.
Other information on the batteries includes.
- The batteries are used in regenerative braking.
- Batteries can be charged by the alternator or the pantoraph.
- Each locomotive has two batteries slightly bigger than a large suitcase.
Nothing is said about the capacity of the batteries, but each could be say 200 litres in size.
I have looked up manufacturers of lithium-titanate batteries and there is a Swiss manufacturer of the batteries called Leclanche, which has this data sheet, that describes a LT30 Power cell 30Ah.
- This small cell is 285 mm x 178.5 mm x 12 mm.
- It has a storage capacity of 65 Wh
- It has an expedited lifetime of greater than 15,000 cycles.
- It has an energy density of 60 Wh/Kg or 135 Wh/litre
These cells can be built up into much larger batteries.
- A large suitcase is 150 litres and this volume would hold 20 kWh and weigh 333 Kg.
- A battery of 300 litres would hold 40 kWh. Is this a large Swiss suitcase?
- A box 2.5 metres x 1 metre x 0.3 metres underneath a train would hold 100 kWh and weigh 1.7 tonnes
These batteries with their fast charge and discharge are almost like supercapacitors.
, It would appear that, if the large suitcase batteries are used the Class 93 locomotive will have an energy storage capacity of 80 kWh.
But this is said about Class 93 locomotive performance..
LTO batteries were chosen because they offer a rapid recharge and can maintain line speed while climbing a gradient, and will recharge when running downhill.
Looking at the batteries, they could provide up to around 40 kW of extra power for perhaps half an hour to help the train climb a gradient and then recharge using regenerative braking or the diesel alternator.
This is a hybrid vehicle, with all the efficiency advantages.
The article does say, that with a light load, the locomotives can do 110 mph on hybrid. Nothing is said about what is a light load.
Could it be a rake of five modern Mark 5A coaches?
In Thoughts On A Battery Electric Class 88 Locomotive On TransPennine Routes, I said this.
It is worth looking at the kinetic energy of a Class 88 locomotive hauling five forty-three tonne CAF Mark 5A coaches containing a full load of 340 passengers, who each weigh 90 Kg with baggage, bikes and buggies. This gives a total weight would be 331.7 tonnes.
The kinetic energy of the train would be as follows for various speeds.
90 mph – 75 kWh
100 mph – 92 kWh
110 mph – 111 kWh
125 mph – 144 kWhThe increase in energy is because kinetic energy is proportional to the square of the speed.
There would be little difference in this calculation, using a Class 93 locomotive, which is only a tonne heavier. The kinetic energy at 100 mph, would be 93 kWh.
This could be very convenient, as it looks like the battery capacity could be almost as large as the kinetic energy of a fully-loaded train.
A train stopping in a station without electrification, would cut diesel running drammatically in the station and when accelerating away.
Similar Weight And Axle Load To A Class 88 Locomotive
The article states that the locomotive will weight 87 tonnes, as opposed to the 86 tonnes of a Class 88 locomotive.
As both locomotives have four axles, this would mean that their axle loading is almost the same.
So anywhere the Class 88 locomotive can go, is most likely to be territory suitable for the Class 93 locomotive.
Again, this must make certification easier.
A Modular Design
In a rail forum, members were saying that the Class 93 locomotive has a modular design.
So will we see other specifications with different sized diesel engines and batteries?
The TransPennine routes, for example, might need a locomotive with a smaller diesel engine, more battery capacity and a 125 mph-capability for the East Coast Main Line.
Stadler have said they specialise in niche markets. Have they developed the tailor-made locomotive?
Power Of Various Locomotives
These are various UK locomotives and their power levels in megawatts.
- Class 43 – Diesel – 1.7
- Class 66 – Diesel – 2.4
- Class 67 – Diesel – 2.4
- Class 68 – Diesel – 2.8
- Class 88 – Electric – 4
- Class 88 – Diesel – 0.7
- Class 90 – Electric – 3.9
- Class 91 – Electric – 4.8
- Class 93 – Electric – 4
- Class 93 – Diesel – 0.9
- Class 93 – Hybrid – 1.3
The interesting figure, is that the Class 93 locomotive has 53 % of the diesel power of a Class 43 locomotive from an InterCity 125. The difference could probably be made up at times using battery power, where needed. The batteries could be partly recharged using regenerative braking.
Could The Locomotive Be Uprated To 125 mph?
Consider.
- The UK has successfully run 125 mph Class 43 and 91 locomotives for many years.
- Stadler has built trains that run at that speed.
- Mark 3, Mark 4 and Mark 5A coaches are all certified for 125 mph.
- There are hundreds of miles of track in the UK, where 125 mph running is possible.
I would think it very unlikely, that the engineers designing the Class 93 locomotive, ruled out the possibility of 125 mph running in the future!
Only Stadler will know!
Could A Battery/Electric Version Of The Locomotive Be Created?
I don’t see why not!
The diesel engine, fuel, exhaust and cooling systems and some ancilliary systems could all be removed and be replaced with an equivalent weight of batteries.
As the C27 diesel engine in a Class 88 locomotive weighs almost seven tonnes, I suspect a ten tonne battery would be possible.
Given the current typical energy density and using the Leclanche figures, this would mean that the batteries would have a total capacity of around 700-700 kWh.
Possible Uses Of The Class 93 Locomotive
The Rail Magazine article goes on to detail some of the uses of a Class 93 locomotive.
Express Freight
Karl Watts says this.
They can operate express freight. In Europe, there are vehicles capable of 100 mph running, and these are perfect for high-speed domestic freight. We have been running intermodals at 75 mph since the 1960s – It’s time to change that.
The locomotive would certainly be able to haul express freight at 100 mph on an electrified main line.
Note the following.
- This would greatly help with freight between Felixstowe and London on the 100 mph Great Eastern Main Line.
- Running freight trains at 100 mph on the major electrified lines would increase capacity, of the lines.
- Ports and freight terminals wouldn’t need to be electrified.
Overall, the proportion of freight mileage, where electric power was used, would grow significantly.
Electrification Gap Jumping
In Thoughts On A Battery/Electric Replacement For A Class 66 Locomotive, I gave a list of typical gaps in the electrification in the UK.
- Didcot and Birmingham – Around two-and-a-half hours
- Didcot and Coventry – Just under two hours
- Felixstowe and Ipswich – Around an hour
- Haughley Junction and Peterborough – Around two hours
- Southampton and Reading – Around one-and-a-half hours
- Werrington Junction and Doncaster via Lincoln – Around two hours
- Werrington Junction and Nuneaton – Just under two hours
How many of these gaps could be bridged by a Class 93 locomotive working in a diesel hybrid mode?
It should be noted, that many of the busiest gaps are in the flatter Eastern areas of England.
I’m sure Stadler and Rail Operations Group have done extensive simulation of possible routes and know where the locomotives are best suited.
Class 66 Locomotive Replacement
I suspect that several of these locomotives will end up replacing duties currently done by Class 66 locomotives.
It could haul an intermodal freight from Felixstowe to Manchester, Liverpool, Glasgow or Doncaster, using electrification where it exists.
And do it at a speed of 100 mph, where speed limits allow!
No other locomotive on the UK network could do that!
Use On Electrified Urban Freight Routes
Near to where I live there are two electrified lines passing through North London; the North London Line and the Gospel Oak To Barking Line.
Both lines have several freight trains a day passing through, that are still hauled by diesel locomotives.
There are other urban freight routes around the UK, where despite electrification, polluting diesel locomotives are still used.
Class 93 locomotives would be an ideal environmentally-friendly replacement locomotive on these routes.
Thunderbird Duties
Karl Watts says this.
They can be used for network recovery as a more comprehensive Thunderbird. Currently, stand-by locomotives are hired or used by an operator to rescue its own trains, but these would be available for anything or anyone. I have sopken to Network Rail about this and they need convincing. But as the network gets busier, so it will be that one failure causes chaos.
Perhaps, a better method for recovering failed trains could be developed.
Passenger Trains
Karl Watts says this.
I can say that the 93s’ feature n two franchise bids, although I cannot say which, due to non-disclosure agreements.
We can only speculate!
Class 93 locomotives could replace the Class 68 locomotives on TransPennine Express services between Liverpool and Scarborough, where Mark 5A coaches will be used.
- Electric mode could be used between Liverpool and Stalybridge and on the East Coast Main Line.
- Diesel or hybrid mode would be used where needed.
- If the locomotives could be uprated to 125 mph, that would help on the East Coast Main Line.
There are certainly, redundant Mark 4 coaches or new Mark 5A coaches that could be used to provide services.
An InterCity 125 For the Twenty-First Century
The InterCity 125 is a masterpiece of engineering, that passengers love.
One of the reasons for the success, is the superb dynamics of the train, which gives them a very comfortable ride.
Could it be that by putting two Class 93 locomotives at each end of a rake of suitable coaches could create a 125 mph train, with the same faultless dynamics?
The answer is probably yes, but in many cases either half-length trains or bi-mode multiple units may be a more affordable or capable train.
The locomotive certainly gives a lot of flexibility.
Conclusion
This is going to be a very useful locomotive.
This was the last paragraph of the printed article, as spoken by Karl Watts.
I don’t think I will be ordering only ten or 20 – there will be more.
I have registered 93001 to 93050.
The word hybrid opens the door.
I think this might be the third member of a very large and widespread family.
The Anonymous Widower
